Srimad Bhagavatham-6.1.43, 44, & 45.

etaih = by all these (witnesses, beginning from the sun-god); adharmah = deviation from the regulative principles; vijnatah = is known; sthanam = the proper place; dandasya = of punishment; yujyate = is accepted as; sarve = all; karma anurodhena = with consideration of the activities performed; dandam = punishment; arhanti = deserve; karinah = the performers of sinful activities.The candidates for punishment are those who are confirmed by these many witnesses to have deviated from their prescribed regulative duties. Everyone engaged in fruitive activities is suitable to be subjected to punishment according to his sinful acts.

O inhabitants of Vaikuntam, you are sinless, but those within this material world are all karmīs, whether acting piously or impiously. Both kinds of action are possible for them because they are contaminated by the three modes of nature and must act accordingly. One who has accepted a material body cannot be inactive, and sinful action is inevitable for one acting under the modes of material nature. Therefore all the living entities within this material world are punishable.

The Vishnudutas protect the devotees of the Lord from the hands of enemies, from envious persons and even from my jurisdiction, as well as from natural disturbances.

annam = food;
caranam = of those that move on wings;
acarah = the nonmoving (fruits and flowers);
hi = indeed;
apadah = the living entities without legs, like the grass;
pada - carinam = of the animals who move on legs, like the cows and buffalo;
ahastah = animals without hands;
hasta-yuktanam = of the animals with hands, like the tigers;
dvi-padam = of human beings, who have two legs;
ca = and;
catush-padah = the four-legged animals like the goat.

By nature’s arrangement, fruits and flowers are considered the food of insects and birds; grass and other legless living entities are meant to be the food of four-legged animals like cows and buffalo; animals that cannot use their front legs as hands are meant to be the food of animals like tigers, which have claws; and four-legged animals lik…
